Has anyone already tried to book on Iberia or Aer Lingus using a 2-4-1? I've got an outward LGW-BGI in the system for October 23 and with be calling BA to grab EZE-LHR for the return mid December in a couple of weeks. This change would hugely increase the choice of flights for EZE-LHR, albeit mainly with a change in MAD.
I'm assuming that LGW-BGI with EZE-LHR is valid for a 2-4-1 open jaw?
